BOTTLE-CLOSING CAP.

SPECIFICATION forming part of Letters Patent No. 651,369, dated June 12,1900.

Application filed October 5, 1399.

To all whom, it may concern.-

Be it known that I, PHILIP LINDEMEYR, a resident of the city ofBaltimore, in the State of Maryland, have invented certain new and.useful Improvements in Bottle-Closing Caps;

. and I do hereby declare the following to be a full, clear, and exactdescription of the invent-ion, such as will enable others skilled in theart to which it pertains to make and use the same.

The invention relates to caps for closing bottles and the like, and hasfor its object to provide for the more uniform distribution of metal bycrimping the cap-flanges uniformly throughout their Whole extent, saidflanges having lugs formed inthe crimped portions.

The invention consists in the construction hereinafter described andpointed out.

In the accompanying drawings, Figure 1 is a side elevation of theimproved cap. Fig. 2 is a perspective. Fig. 3 is a central longitudinalsection. Fig. 4 is a section on line 4 4 of Fig. 1.

Numeral 1 denotes a cap-flange provided with crimps or corrugationsthroughout its whole extent.

2 denotes a shoulder formed in the cap which, among other functions,adds to the rigidity of the cap and tends to avoid spreading of thesame.

3 denotes indentations in the cap above the shoulder. In some casesthese may be omitted, and also the shoulder, if desired.

t denotes lugs formed in the crimped flange and preferably retaining thecrimps. They are produced by slitting the flange before or aftercrimping the cap and indenting a portion of the metal adjacent the slit.The sharp metal edge of a lug thus formed is held to the correspondinglug or incline of Serial No. 732,741. (No model.)

'the bottle without slipping,and very securely,

and such a lug can yield when necessary to permit screwing on of thecap.

The crimps in the cap-lug provide that they can be indented with lessdrawing of the metal and with less danger of fracture. If the crimps inthe lug in its initial state are not entirely removed by indenting thesame, but remain in the lugs, the latter have a greater extent in aradial direction and have, therefore, a greater extent of bearing edge.

I am aware that longitudinally-crimped caps have been provided withplain faces intermediate the crimps, said faces havinginwardly-projecting lugs and such construction is not of the presentinvention, which is characterized by lugs formed transversely of thecrimps in caps having no plain faces in termediate said crimps. Suchplain faces have heretofore been regarded as necessary, but I have foundthat lugs can be formed in the crimped portion, and said lugs havegreater strength and a better bearing-surface.

Having'thus described my invention, what I claim is 1. A cap for closingbottles and the like having its flange longitudinally crimped and havinglugs formed in the crimps.

2. A cap for closing bottles and the like having its flangelongitudinally crimped and lugs formed in the crimps, said lugs beingformed by slitting the metal circumferentially and indenting it adjacentthe slits.

In testimony whereof I have signed this specification in the presence oftwo subscribin g witnesses.
